Photomicrograph of histological sections: (A) histological detailed features of the biomaterials (BIO, BFL, CLN, and LBP) and surrounding tissues in the central region of the defect at 14 days (HE, original magnification 40x); (B) mallory trichrome staining (original magnification 40x). CT: connective tissue; NB: newly formed bone; OLC: osteoblastic line cells; OT: osteoid tissue.
